SCP-1938 in an active state, containing several instances of SCP-1938-2.

Item #: SCP-1938

Object Class: Safe

Special Containment Procedures: SCP-1938 should be held in a standard Safe object containment cell. The cell is to be sealed in such a way as to prevent water from being introduced into the cell. No aquatic life apart from SCP-1938-1 should be placed into SCP-1938.

Description: SCP-1938 is an aquarium, capable of holding up to 450 liters of water. It weighs approximately 25 kilograms when it is empty, and 55 kilograms when it has been filled. SCP-1938''s area measures 151 x 61 cm, and is 63 cm in height.

SCP-1938''s anomalous effect will activate if the inside of the tank is filled with water. If this occurs, SCP-1938 will appear to contain a filter, thermometer, a layer of pebbles at the bottom, and several pieces of coral. In addition, several fish (hereafter referred to as SCP-1938-1) will materialize inside the tank. These fish do not match any known terrestrial species of marine life. Instances of SCP-1938-1 will disappear if SCP-1938 is drained of water. Behavior patterns of SCP-1938-1 resemble those of Botia macracantha.

Additionally, if any person (hereafter referred to as "the user") submerges any portion of their body into SCP-1938, they will appear to vanish for approximately fifteen minutes, after which they will re-appear in a spot within 15 meters of their original location. Users will report that they were teleported into SCP-1938 in the form of a small fish, and that they were in a feudal-style underwater civilization populated by instances of SCP-1938-1. This civilization is usually described as having characteristics similar to the traditional interpretation of a "Utopia", with every instance of SCP-1938-1 reporting great satisfaction with their life and an eagerness to positively interact with the user. The time the user perceives having spent in SCP-1938 ranges from 2 hours to one week. Note that SCP-1938-1''s behavior does not reflect the observations of the user during this time.

If any species of fish that are not instances of SCP-1938-1 are introduced into the tank, all instances of SCP-1938-1 will immediately change into copies of this introduced species. These new organisms (hereafter referred to as SCP-1938-2) will behave in a much more erratic manner than instances of SCP-1938-1, but apart from behavior and appearance, they share the properties of SCP-1938-1.

However, if the user attempts to use SCP-1938 while it is populated by SCP-1938-2, they will have a different experience. Users will report that they found themselves in an area described as similar to the location found when using SCP-1938-1, but in a state of severe instability. This area will be populated by instances of SCP-1938-2, which are invariably hostile towards the user. In addition, users will report that their experiences in SCP-1938 last for an extended amount of time, with the longest reported being approximately ████ days. Note that no matter what users experience during this time, they will not sustain any injuries.

Addendum: This note was recovered with SCP-1938.
